TORONTO, Feb. 19, 2014 /CNW/ - IAMGOLD Corporation ("IAMGOLD" or "the Company") today announced its 2013 year-end mineral
reserve and resource statement. Highlights include:
-
Total attributable proven and probable gold reserves decreased by 11% or
1.2 million ounces (after depletion) to 10.1 million ounces of gold at
the end of 2013 mainly impacted by Rosebel (-1.4 million ounces) as a
result of mining parameter changes reflecting higher costs associated
to hard rock mining and Sadiola (-0.7 million ounces) due to change in
gold price assumptions used, partially offset by an increase at
Essakane (+0.8 million ounces) due to positive drilling results. The
weighted average grade of the proven and probable mineral reserves has
increased from 1.1 g/t Au to 1.2 g/t Au.
-
Total attributable measured and indicated gold resources (inclusive of
reserves) increased by 4% or 0.8 million ounces at 23.4 million ounces
of gold at the end of 2013 mainly due to the addition of Boto (+1.1
million ounces) and Essakane (+0.6 million ounces) as a result of
positive drilling results, partially offset by Rosebel (-0.3 million
ounces) due to mining parameter changes in pits, reflecting the higher
costs associated with harder rock mining and Sadiola (-0.5 million
ounces) due to change in gold price assumptions used. The weighted
average grade of the proven and probable mineral resources remained at
1.1 g/t Au.
-
The niobium probable mineral reserves have decreased by 3% to 1,707
million kilograms of contained Nb2O5 based on the block caving scenario.
-
Niobium measured and indicated resources have increased by 3% to 2.7
billion kilograms of contained Nb2O5 compared to the prior year.
Steve Letwin, President and CEO of IAMGOLD, said, "Amidst a $125 million
company-wide cost reduction program that included a $41 million cut to
the exploration plan for the year, the exploration and mine site
geology teams made remarkable progress on a number of fronts. The
attributable probable mineral reserves at Essakane increased by 25%
after depletion from 3.3 to 4.1 million ounces, as additional resources
were found at depth and laterally in the mine pit and the model
reflected more continuity in some zones. In addition, the average
grade of the mineral reserves at Essakane increased from 1.00 to 1.12
g/t Au. The Westwood mineral reserves increased by over 40% from
348,000 to 510,000 ounces from a positive conversion of mineral
resources, which also saw a net increase as a result of a successful
2013 drilling campaign.
"On the greenfield front, a maiden resource was declared on July 29,
2013 at the Boto project in Senegal, in close proximity to some of our
exploration interests in Mali. We are also excited about the progress
to date and the work underway at the Pitangui Project in Brazil with a
delineation drilling program advancing the project towards an initial
mineral resource estimate. Several new option agreements have also
been reached with exploration companies with promising projects in
regions such as Colombia and in Canada. Although early stage, these
projects present drill ready targets with potentially short time lines
to discovery and reflect the hard work of our exploration team to
continue to identify and build a pipeline of growth opportunities."
On January 22, 2013, the Company announced an updated NI 43-101
compliant resource estimate for the Côté Gold deposit in Ontario
comprising indicated resources of 269 million tonnes, averaging 0.88
g/t Au for 7.61 million ounces and inferred resources of 44 million
tonnes, averaging 0.74 g/t Au for 1.04 million ounces. The updated
resource estimate, based on a cut-off grade of 0.30 g/t Au, represents
a 114% increase in indicated resources in comparison to the previous
estimate announced October 4, 2012.
NIOBIUM
In 2013, more than 14,800 metres of underground diamond drilling were
completed as part of the expansion program with the objective to
increase the confidence of the resources and support a five-year
transition strategy towards the planned expansion of the operation.
Results were as expected. In addition, over 6,900 metres of surface
exploration and condemnation drilling were completed to acquire further
geological and geotechnical information to assist in the design of
planned mine development and surface infrastructure. The drilling
programs ended in late August. Metallurgical test work was carried out
continuously during the year to confirm estimated recoveries as part of
the resource estimation process.
As of December 31, 2013, based on the block caving scenario, the niobium
probable mineral reserves were 1.7 billion kilograms of contained Nb2O5 and the measured and indicated resources increased from 2.56 to 2.65
billion kilograms.
RARE EARTH ELEMENTS
As amended on September 19, 2013, IAMGOLD announced an indicated
resource or 531.4 million tonnes at an average grade of 1.64% Total
Rare Earth Oxides ("TREO") and inferred resource of 527.2 million
tonnes at an average grade of 1.83% TREO estimated on the rare earth
elements ("REE") zone located adjacent to and one kilometre north of
its Niobec niobium mine. There were no changes made in 2013 to the
estimated mineral resources previously announced.
Notes to Investors Regarding the Use of Resources
Cautionary Note to Investors Concerning Estimates of Measured and
Indicated Resources
This news release uses the terms "measured resources" and "indicated
resources". We advise investors that while those terms are recognized
and required by Canadian regulations, the United States Securities and
Exchange Commission (the "SEC") does not recognize them. Investors are
cautioned not to assume that any part or all of mineral deposits in
these categories will ever be converted into reserves.
Cautionary Note to Investors Concerning Estimates of Inferred Resources
This news release also uses the term "inferred resources". We advise
investors that while this term is recognized and required by Canadian
regulations, the SEC does not recognize it. "Inferred resources" have a
great amount of uncertainty as to their existence, and great
uncertainty as to their economic and legal feasibility. It cannot be
assumed that all or any part of an inferred mineral resource will ever
be upgraded to a higher category. Under Canadian rules, estimates of
inferred mineral resources may not form the basis of feasibility or
pre-feasibility studies, except in rare cases. Investors are cautioned
not to assume that part or all of an inferred resource exists, or is
economically or legally mineable.
Scientific and Technical Disclosure
IAMGOLD is reporting mineral resource and reserve estimates in
accordance with the CIM guidelines for the estimation, classification
and reporting of resources and reserves.
Note: Mineral reserves and mineral resources for IAMGOLD's gold mines
for the 2013 year-end statement were estimated using a $1,400 per ounce
gold price (unless otherwise indicated in the notes in Table 1) for
mineral reserves and a $1,500 per ounce price for mineral resources
(unless otherwise indicated in the notes in Table 1). For open pit
operations, gold resources are constrained within an economic pit
shell.
Note: Mineral reserves have been estimated as at December 31, 2013 using
the block caving scenario using $45 per kg of Niobium and include
dilution material. Mineral resources have been estimated using a cutoff
of 0.20% Nb2O5 per tonne (before recovery) under the block caving scenario.
Cautionary Note to U.S. Investors
The SEC limits disclosure for U.S. reporting purposes to mineral
deposits that a company can economically and legally extract or
produce. IAMGOLD uses certain terms in this news release, such as
"measured," "indicated," or "inferred," which may not be consistent
with the reserve definitions established by the SEC. U.S. investors
are urged to consider closely the disclosure in the IAMGOLD Annual
Reports on Forms 40-F. You can review and obtain copies of these
filings from the SEC's website at http://www.sec.gov/edgar.shtml or by contacting the Investor Relations department.
The Canadian Securities Administrators' National Instrument 43-101 ("NI
43-101") requires mining companies to disclose reserves and resources
using the subcategories of "proven" reserves, "probable" reserves,
"measured" resources, "indicated" resources and "inferred" resources.
Mineral resources that are not mineral reserves do not demonstrate
economic viability.
A mineral reserve is the economically mineable part of a measured or
indicated mineral resource demonstrated by at least a preliminary
feasibility study. This study must include adequate information on
mining, processing, metallurgical, economic and other relevant factors
that demonstrate, at the time of reporting, that economic extraction
can be justified. A mineral reserve includes diluting materials and
allows for losses that may occur when the material is mined. A proven
mineral reserve is the economically mineable part of a measured mineral
resource demonstrated by at least a preliminary feasibility study. A
probable mineral reserve is the economically mineable part of an
indicated, and in some circumstances, a measured mineral resource
demonstrated by at least a preliminary feasibility study.
A mineral resource is a concentration or occurrence of natural, solid,
inorganic material, or natural, solid fossilized organic material
including base and precious metals in or on the Earth's crust in such
form and quantity and of such a grade or quality that it has reasonable
prospects for economic extraction. The location, quantity, grade,
geological characteristics and continuity of a mineral resource are
known, estimated or interpreted from specific geological evidence and
knowledge. A measured mineral resource is that part of a mineral
resource for which quantity, grade or quality, densities, shape and
physical characteristics are so well established that they can be
estimated with confidence sufficient to allow the appropriate
application of technical and economic parameters, to support production
planning and evaluation of the economic viability of the deposit. The
estimate is based on detailed and reliable exploration, sampling and
testing information gathered through appropriate techniques from
locations such as outcrops, trenches, pits, workings and drill holes
that are spaced closely enough to confirm both geological and grade
continuity. An indicated mineral resource is that part of a mineral
resource for which quantity, grade or quality, densities, shape and
physical characteristics can be estimated with a level of confidence
sufficient to allow the appropriate application of technical and
economic parameters, to support mine planning and evaluation of the
economic viability of the deposit. The estimate is based on detailed
and reliable exploration and testing information gathered through
appropriate techniques from locations such as outcrops, trenches, pits,
workings and drill holes that are spaced closely enough for geological
and grade continuity to be reasonably assumed. An inferred mineral
resource is that part of a mineral resource for which quantity and
grade or quality can be estimated on the basis of geological evidence
and limited sampling and reasonably assumed, but not verified,
geological and grade continuity. The estimate is based on limited
information and sampling gathered through appropriate techniques from
locations such as outcrops, trenches, pits, workings and drill holes.
Mineral resources which are not mineral reserves do not have
demonstrated economic viability.
Investors are cautioned not to assume that part or all of an inferred
resource exists, or is economically or legally mineable.
A feasibility study is a comprehensive technical and economic study of
the selected development option for a mineral project that includes
appropriately detailed assessments of realistically assumed mining,
processing, metallurgical, economic, marketing, legal, environmental,
social and governmental considerations together with any other relevant
operational factors and detailed financial analysis, that are
necessary to demonstrate at the time of reporting that extraction is
reasonably justified (economically mineable). The results of the study
may reasonably serve as the basis for a final decision by a proponent
or financial institution to proceed with, or finance, the development
of the project. The confidence level of the study will be higher than
that of a Pre-Feasibility Study.
A Pre-Feasibility Study is a comprehensive study of a range of options
for the technical and economic viability of a mineral project that has
advanced to a stage where a preferred mining method, in the case of
underground mining, or the pit configuration, in the case of an open
pit, is established and an effective method of mineral processing is
determined. It includes a financial analysis based on reasonable
assumptions on mining, processing, metallurgical, economic, marketing,
legal, environmental, social and governmental considerations and the
evaluation of any other relevant factors which are sufficient for a
qualified person, acting reasonably, to determine if all or part of the
Mineral Resource may be classified as a Mineral Reserve.

In underground operations, mineral resources contain similar dilution
and mining recovery as mineral reserves, except for Westwood where 35%
dilution was applied to the reserves.
|
(3)
|
In mining operations, measured and indicated resources that are not
mineral reserves are considered uneconomic at the price used for
reserve estimations but are deemed to have a reasonable prospect of
economic extraction.

Although "measured resources", "indicated resources" and "inferred
resources" are categories of mineralization that are recognized and
required to be disclosed under Canadian regulations, the SEC does not
recognize them. Disclosure of contained ounces is permitted under
Canadian regulations; however, the SEC generally permits resources to
be reported only as in place tonnage and grade. See "Cautionary Note
to U.S. Investors Regarding Mineral Reporting Standards".

Mineral reserves have been estimated as at December 31, 2013 under the
block caving scenario using $45 per kg of Niobium and include dilution
material. Mineral resources have been estimated using a cutoff of 0.20%
Nb2O5 per tonne (before recovery) under the block caving scenario.
|

|
There is a large volume of the material within the planned block caving
that has a Measured Resource classification. However, due to the
uncertainty associated with estimating material movement within the
cave, a Probable classification has been applied to the reserve because
of the uncertainty.

A small amount of Inferred and unclassified mineral resource material
will be mined from the block caving scenario and segregation of the
material is not possible. A conservative 0% Nb2O5 was applied to that material.
